Updating Adobe Acrobat or your operating system can sometimes cause the program to stop working. For some, Adobe Acrobat Pro not opening is the result, or the app launches in the background without showing a window. This section explains why updates can cause these issues and how to resolve them.

Common Update-Related Symptoms

After an update, users may notice:

• Adobe Acrobat won’t open at all after launching.
• Acrobat stops responding or crashes immediately.
• Acrobat opens in the background but no window appears.
• PDFs fail to load even though the app starts.
• Acrobat worked fine before the update but now fails to start.

Why Updates Can Break Adobe Acrobat

Updates, while designed to improve features and security, sometimes conflict with system settings or older files:

• The updated Acrobat version may clash with existing system files.
• Switching from Classic Acrobat to the New Acrobat interface can create compatibility issues.
• Preferences may reset or become corrupted during the update.
• Windows or macOS updates can change permissions, services, or registry settings that Acrobat depends on.

What You Can Try First

1. Switch Between New Acrobat and Classic Acrobat

Some updates default to the New Acrobat interface, which may not be fully compatible with your system. Opening Classic Acrobat can help confirm whether the problem is interface-related.

1. Locate both New Acrobat and Classic Acrobat on your system.
2. Try launching Classic Acrobat to check if PDFs open correctly.
3. If Classic works, continue using it until Adobe releases a compatible update or patch.

2. Restart Your Computer to Complete Pending Updates

Incomplete OS or Acrobat updates can prevent the app from opening. Restarting makes sure that updates are fully applied.

1. Save all your work.
2. Click Start > Power > Restart (Windows) or Apple menu > Restart (Mac).
3. After the restart, try opening Adobe Acrobat again.

3. Reset Acrobat Preferences to Clear Update Conflicts

1. Close Adobe Acrobat completely.
2. Press Windows + R (Windows) or Command + Shift + G (Mac).
3. Navigate to the preferences folder:
   • Windows: %appdata%\Adobe\Acrobat\[version]\
   • Mac: ~/Library/Preferences/Adobe/Acrobat/[version]/
4. Rename or delete the Preferences folder.
5. Restart Adobe Acrobat to generate a new preferences folder.

4. Roll Back the Recent Update

If the app worked perfectly before an OS or Acrobat update, rolling back may restore functionality.

Steps (Windows):

1. Go to Settings > Update & Security > Windows Update > Update history > Uninstall updates.

2. Select the recent update that caused the issue and uninstall it.
3. Restart your computer and test Adobe Acrobat.

Steps (Mac):

1. Open System Settings > General > Software Update > More info.
2. If a recent update is listed, click Restore or follow Apple’s instructions for rollback.
3. Open Acrobat and check functionality.

5. Reinstall Adobe Acrobat if Problems Persist

If none of the above works, reinstalling Acrobat makes sure all files are updated and compatible.

1. Uninstall Adobe Acrobat from Control Panel (Windows) or Applications folder (Mac).
2. Download the latest version from the official Adobe website.
3. Install Acrobat and sign in with your Adobe account.
4. Test PDF files to confirm that the update issue is resolved.
